For last few months I have been pruning the forum from spam registrations.I don't know whether these are robotic registrations, or just some idiots (mostly from China, but also from Latvia, Ukraine and Russia).Honestly, reading through a long list of their nicknames and passwords and following up their IP addresses is not a very entertaining job.Doing that work manually takes time and still is not 100% error prone. Thus I may have allowed a few spammers on the forum inadvertently, and if they cause any inconvenience to us I apologize in advance and thank you for your patience.
